Debug AC timing specifications
Table 41 lists specifications for the debug AC timing parameters shown in Figure 41 and Table 42.
All debug signals use pad type pad_msr except for PSTCLK which use pad type pad_fsr. The following timing specifications
assume a pad slew rate setting of 11 and a load of 50 pF.1
Figure 41. Real-time trace AC timing
Figure 42. BDM serial port AC timing
1.These timing parameters are specified assuming maximum operating frequency and the fastest pad slew rate setting
(11). When operating this interface at lower frequencies, increase the slew rate by using the 10, 01, or 00 setting to
increase edge rise and fall times, thus reducing EMI.
